M invention relates to painting apparatus and as-for its rinci alo ject, the provision of an improve simp 'lied'painting machine.

Another obect, is to provide a painting maa chine adapte to be oprated by its engagement with the article ing painted.

Another object is to provide a simplified means for applying a protective paint coating to board lumber.

Another object is to paint board lumber during the normal handling thereof and without'the expenditure of comparatively reater time than is required for handling suc lumber without painting.

Other ob]ects and features will appear from the consideration of the following detailed description taken with the accompanying drawings in which- I Fig. 1 is a side elevational view partially broken away to conserve space, showing one form of my paintin machine, and

Fig. 2 in a plan view of the machine with the superstructure thereof removed. l

My invention has been directed principally to the painting of railroad car lumber. This lumber has in the past been stored at the car shops without any protection. B means of my invention, l paint three sides o the boards as they are removed from the car and take practically no more time to paint and pi e the lumber, than has been-taken in the past to simply remove it from the cars and pile it for storage.

As the hoard lumber is removed from av car, it is placed upon suitable runways where it proceeds by gravity or by being pushed by workmen to the osition in which it is to be stored.. At the en of the runway, I insert a painting apparatus which -requires no 4power connection and which is adapted to supply paint to the boards as they pass in contact therewith.` No extra handling is required and the boards not only receive a protecting coating but this coating also acts as a primer or first coat, therefore saving a great deal of time in the painting operation after they have been applied tothe sides and ends of a car.

Referring now to the drawings, I villustrate a usual form of runway adapted to con-4 with the top of the rollers 12. The rotary vey the board lumber to a storage position. lhe runway comprises a framework 10 havmlgi upper longitudinal members 11--11 in w ch are ]ournaled the axes of a pluralit of rollers 12--12. A bracing rod 13 extendz between uprights of the frame and the longitudinal members 11.

My painting machine is adapted to be mounted on a section of this conveyor framework and in the drawingsv lshow it so mounted. l can of course em lo `an entirely separate framework but it is apparent that my purpose will be served more readily by adopting the structure shown.

A 'lower reservoir 16 is secured between the two members 11, in any suitable manner, so as vto depend below the upper level. of the framework. An upper reservoir 17 is' secured to a air of su porting brackets 18 which are a secure on the members 11. A rotary brush 19 is mounted to revolve upon an axis 21 so that its lower surface rojects into the paint lin the reservoir 16 and) its upper surface is slightly above a line coinciding brush 19 is constructed of sim le and inexpensive materials." l have emp oyed for this urpose, a wooden roller with a comparativey heavy Brussels car et secured on the outside thereof with the ristles extending out- Ward-ly.

lt is ap arent, a board passing over the roller` 19 will pick up a coating of aint therefrom, but in order to obtain the est results I provide guides for the board.

The centering guides are two in number and comprise spring guides 22 provided with triangular plates 23 which are pivoted to studs 24 secured in the longitudinal frame members 11. The triangular sections 23 have a plurality of holes 25 arran ed at equal distances from the pivot 24, an are adapted to cooperate. with a single aperture 26 in the .members 11 for regulating the positions of the guides 22. By withdrawing pins 27, the trian ular sections 23 may be moved about the pivots 24'until another one of the holes 25 registers with the aperture 26 in the members 11. The pin is then reinserted and the guide has an adjustment for a different size 100 of board. The guides are exactly alike except for being reversed, and each is preferably set when a different size board must be accommodated.

I also provide means for holding the board ilmly against the roller 19. On each longitudinalframe member 11, a bell crank lever 28 i's` secured on a pivot 29 and a roller 31 is rotatably secured between the two bell cranks. e A guide 32 is secured to the frame and has a slotted ortion in which one arm of thebell crank 1s adapted to extend. A coil spring 33 has one end secured -to the forward end of the bell crank lever and the frame, so that at all times a downward pressure of roller 31 takes place. The 'pressure roller 31 therefore serves to keep the board at all times in engagement with the roller brush 19; while a roller 34 identical with the roller 12 described above, serves to prevent too great a pressure of the board against the roller brush 19.

The sides of the board are painted by roller brushes 35-35 secured on arms 36 which are pivoted to the main frame 37. The two arms 36 have small end extensions between which a tension spring 38 is secured, thereby tending at all times to bring the two side brushes 35 together. But. it is notadvisable to permit the'brush'es 35 to come too close to each other as they may then interfere with the passage of the board therethrough. Accordingly on each arm 36, there is pivoted a rod 41 which is reciprocable in a guide 42. The rod 41 has a plurality of vertically disposed apertures 43 adapted to receive a pin whereby the inner movement of the arm 36 is limited, by outside-movement thereof permitted to any extent within the limits of thev design.

Each of the brushes 35 is supplied with paint from the upper reservoir 17 through avertically disposed pipe 45. Midway of the pipe 45, a valve 46 is inserted having a Valve operating handle 47. A block 48 extending transverse of the machine forms a connection with each one of the valve handles 47 and has, extending therethrough, a trip bar 49. A board passing between tlieibrushes 35 is adapted to engage the lower end of the trip bar 49 and by moving said bar slightly it opens the valves 46 and permits a flow of aint to the brushes 35. The brushes being held in engagement with the sides of the boards, apply a coating of paint thereto.

A pair of wiping brushes 51 is secured to the bracket support 18 for the purpose of wiping the excess paint olf the edges of the board after the paint has been applied by the roller brushes 35. A pair of wiping brushes 52-52 is supported in brackets 53-53 secured to the frame andadapted to wipe the xcesis paint from the under side of the Paint is supplied to the` bottom reservoir 16 from the reservoir 17, the drippings from the brushes 35 being sufiicient to kee the lower reservoir well supplied with paint at all times. Paint is manually supplied to the upper reservoir whenever required. An

over-flow pipe 54 secured through the bottom of the reservoir 16 maintains the paint therein at a constant level. The paint flowing through the top of the over-flow pipe 54 is tra pe `in a suitable receptacle and returne to the reservoir 17. A valve l55 in the over-How pipe can be closed during the time that the receptacle is removed from beneath the over-flow pipe 54 to be emptied into the upper reservoir.

A roller 56 identical with the rollers 12 is provided at the output end of the machine to facilitate painted. A rop board 57 facilitates the removal of the board for the purpose of piling.

The boards may be propelled through the machine by hand, but when the conveyor is positioned on a slant and the boards travel propelled by gravity, they may carry themselves entirely through the machine without the necessity of applying any hand pressure.
